At $29.65, it's used when 3\/4\" copper discharge tubing connects to the check valve, which then threads into the 3\/4\" NPT tank bung. The compression inlet secures the copper tube without threading; the NPT male outlet threads directly into the tank connection. Rated 500 PSIG and 400 degrees F with a 1\/8\" unloader port.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e CTD3434\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection:\u003c\/strong\u003e 3\/4\" Compression tube fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection:\u003c\/strong\u003e 3\/4\" NPT Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating:\u003c\/strong\u003e 500 PSIG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating:\u003c\/strong\u003e 400 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnloader Port:\u003c\/strong\u003e 1\/8\" side port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $29.65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Castair (Spicer, Minnesota)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCTD3434 vs. CTB3434\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD3434 (this listing):\u003c\/strong\u003e Compression tube fitting inlet — 3\/4\" copper tubing inserts into the inlet and is secured by a compression nut and sleeve.
